-LRB- CNN -RRB- -- Girl wonder beats boy wizard .

The Hunger Games trilogy has surpassed the Harry Potter books to become the best-selling series on Amazon.com , the company announced Friday .

`` Since debuting in 2008 , Katniss Everdeen and the Hunger Games have taken the world by storm , much as Harry Potter did a decade before , '' said Sara Nelson , the editorial director of books and Kindle at Amazon , which is the largest bookseller in the United States .

`` Interestingly , this series is only three books versus Harry Potter 's seven , and to achieve this result in just four years is a great testament to both the popularity of the work and , we think , the growth in reading digitally during that time , '' she said .

Katniss is the Hunger Games heroine , whose prowess with arrows and boys has made her the envy of millions of fans . She is the star of the books in Suzanne Collins ' trilogy , `` The Hunger Games , '' `` Catching Fire '' and `` Mockingjay . ''

Author J.K. Rowling penned the Harry Potter series about a boy wizard by the same name and his friends at Hogwarts , a school for witches and wizards . She is currently working on her first novel for adults .

Both series got a big boost from films based off the books .
